WILLIAM GEORGE RUSCOE, OF STAMFORD, CONNECTICUT.

RATCHET-WRENCH.

To all whom it may concern:

Be it known that I, VILLIAM G. Rusoon, a citizen of the United States,and a resident of Stamford, in the county of Fairfield and fitate ofConnecticut, have invented a new and Improved Ratchet-.Vrench, of whichthe following is a full, clear, and exact description.

My invention relates to a new and improved form of ratchet wrench, andan objeet of my invention is to provide a wrench having a wheel, thecircumference of which is recessed to afford a nut-engaging space fornuts of different sizes.

A further object of my invention is to 7 provide a wrench adapted toengage a nut disposed in position ditlicult of access by an ordinarywrench.

A still further object of my invention is to provide a wrench adapted tofit nuts of different sizes, and having means to lock the nut-engagingelement in position.

I attain the above outlined objects by pivoting a wheel to a handle,which wheel has different sized nut-engaging apertures in the peripherythereof, and by rigidly mounting on the side of said wheel, a ratchet,which ratchet is adapted to be engaged by one or both of a pair offingers, to lock the wheel in position, or to permit its movement in aclockwise or anti-clockwise direction, depending upon which way it isdesired to rotate the nut engaged by the apertures.

With the above and other objects in view, as will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts hereinafter fully described,illustratedl in the accompanying drawings, and more particularly pointedout in the appended claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which- Figure 1 is a sideelevation of a preferred embodiment of my invention, parts being brokenaway to show the internal mechanism of one of the fingers and part ofthe handle being broken away; Fig. 2 is an edge View of the device shownin Fig. 1; and Fig.

3 is a perspective view of the wrench e11- gaging a nut, and showing theadaptability Specification of Letters Patent.

of the device for tightening the nut-ima place dillieult of access.

In the drawings I have shown a handle 4 of any preferred length, the endof which handle is formed into a broadened portion 5, which broadenedportion is slotted transversely, as shown at (3. In this slotted portionis mounted a wheel 7 carried by a pin 8, which pin has one end journaledin an extension 9 from the broadened portion 5, the other end of whichpin is journaled in a bracket 10 extending from one face of thebroadened portion 5. Rigidly mounted on the side of the wheel 7 andfastened thereto by means of pins 11, is a ratchet 12, which ratchet isalso mounted on the pin 8. The circumference of the wheel 7 is recessedto form a series of different sized nut-engaging recesses 13. It will beseen that by this arrangement, the wheel 7 is rotated until the recessbest adapted to fit the particular nut is brought into position, and, ifdesired to lock the recess in this position, the ends 1 1 of bolts 15are brought into engagement with the teeth 16 of the ratchet 12, whichends engaging the ratchet at two points, as shown in solid and dottedlines in Fig. 1, prevent the wheel 7 from moving in either direction,thereby holding the recess in its desired position.

The bolts 15 move in pockets 17 disposed longitudinally in the enlargedportion 5 and extending in a direction parallel with and on oppositesides of the bracket 10. Disposed in rear of each of the bolts 15 andhaving one end pressing against said bolt and the other end pressingagainst the bottom of the pocket 17, is a compression spring 18 tendingto force the head 14 into engagement with the ratchet 12.

In order to hold the bolt 15 out of engagement with the ratchet, thereis extending from and at right angles to the bolt, a catch 19, by meansof which the bolt 15 is rotated on its longitudinal axis, to permit thecatch 19 to ride into a pocket 20, in which position the bolt 15 is inengagement with the ratchet 12, or the catch may be withdrawn from therecess 20 and disposed in a channel 21, which channel is disposed atright angles to the pocket 17. In this position of the catch, the boltis withdrawn from its engagement with the ratchet 12, as shown in theupper side of Fig. 1. With but one bolt.

in engagement with the ratchet 12, the wheel lie 7 may be rotated toturn the nut, as shown in Fig. 1, said rotation being in a clockwisedirection. This movement is of advantage where it is difficult to engagea nut to rotate the same. As shown in Fig. 3, it is possible to tightenthe nut by tension, though it is only possible to swing the handle 4-from its position shown in full lines to its position shown in dottedlines in said figure.

-Having thus described my invention, I claim as new and desire to secureby Letters Patent:

In a ratchet wrench having a handle, one end of which is formed into arelatively broad portion slotted transversely, a bracket extending fromsaid handle attached to and parallel with said broadened portion, a

,wheel rotating in said slot and journaled between said broadenedportion and said bracket, a ratchet rigidly afiixed to said wheel, apair of bolts disposed on opposite sides of the bracket, substantiallyT-shaped in cross-section and housed in said broadened portion, meansmaintaining one member of each of said bolts in engagement with saidratchet, to prevent the same from rotating in one direction, saidbroadened portion having a channel therein, and means whereby said boltsmay be rotated on the axis of the member engaging the ratchet, and seatin one channel to hold said member disengaged from said ratchet, saidwheel having a series of differently sized nut-engaging recesses spacedabout the periphery thereof.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

IVILLIAM GEORGE RUSCOE.
